PURPOSE: A speaker system with an improved structure is provided to prevent loss of sound pressure. CONSTITUTION: A speaker system comprises a speaker(1) for radiating sound, a rear sound case(2) coupled to a rear surface of the speaker, and a replacement-type duct(3) which penetrates a front surface of the speaker and is installed within the rear sound case. The replacement-type duct is installed to be attachable/detachable to/from the speaker, and inverts a phase of sound having a specific frequency from among the sounds generated from the rear surface of the speaker and discharges the inverted phase. The duct includes a duct portion(300) shaped as a tube and which is disposed within the rear sound case so as to communicate the rear sound case to the speaker, and a flange portion(301) arranged in front of the duct portion in such a manner that the flange portion is caught at an edge of a duct installation hole formed at the front surface of the speaker so as to define the insertion position of the duct.
